What exactly does roof leak detection entail?

If your roof suddenly starts leaking, it immediately creates stress. Roof leak detection is all about locating invisible cracks or breaks in your roof structure and roofing—before major damage occurs. At Ultrices leak detection, we focus on flat roofs, pitched tiled roofs, bitumen roofs, roof tiles, EPDM roofs, and even green roofs. We use modern, non-destructive detection methods that provide immediate clarity and prevent unnecessary demolition work.

When detecting roof leaks, we scan with advanced tools like thermal imaging cameras and ultrasonic detectors, quickly identify damp patches and thermal bridges, and minimize potential consequential damage. An accurate diagnosis immediately saves time and money, and delivers fast results for individuals, homeowners' associations, property management companies, and businesses.

How does the roof leak detection process work?

The process begins with a thorough inspection. Our team is often deployed 24/7 after a heavy downpour or when residents suddenly notice yellow stains, peeling plaster, or dripping ceilings. We follow a fixed step-by-step plan, so you always know exactly what to expect:

  1. Inventory of complaints We listen to your experiences and immediately analyze where the leak is most likely coming from.
  2. Visual inspection Using a camera, flashlight, and UV light, we assess the visible traces from outside and inside.
  3. Use of detection techniques Depending on the type of roof and the leak, we use thermography, ultrasonic testing, or smoke testing to pinpoint exactly where the water is penetrating the roof.
  4. Reporting and advice Within three days, you'll receive our expert report, complete with photos, measurements, and a concrete action plan. This report is useful for insurers.
  5. Recovery options We provide immediate advice on possible repair options, collaboration with your insurance company, or direct partners in roof maintenance.

The most important techniques for roof leak detection

Roof leaks are often difficult to detect with the naked eye. To speed up the process and prevent failure costs, we employ a wide range of technologies and detection skills:

  • Thermographic camera : We use this to measure temperature differences and locate wet spots, insulation errors or cold bridges without any demolition work.
  • Smoke test By blowing non-toxic smoke under the roof we can immediately see which opening(s) smoke is escaping through, which indicates a leak point.
  • Ultrasonic leak detection : Inaudible sound waves help to detect leaks in drains, roof penetrations or overlapping roof sections.
  • Tracer gas method A mixture of harmless gas is injected under the roof surface. Gas detectors on the surface register exactly where the gas escapes.


Thanks to these techniques, we can locate roof leaks without damaging your home or property. Want to learn more about ultrasonic methods and other smart technologies we use? Visit our comprehensive page about ultrasonic leak detection in practice.

Examples of common roof leak problems

Your roof endures a lot: storms, snow, heat, frost, moss growth, and wear and tear from UV rays. This can lead to all kinds of leaks. Below are some typical scenarios we encounter:

  • Cracks in roof covering : Bitumen roofs can crack after years, allowing rainwater to enter.
  • Broken lead flashings or ridge tiles : Especially with older tiled roofs, loose lead or broken ridge tiles can let in water.
  • Incorrect finishing around dormer or skylight : Incorrect installations often cause water infiltration.
  • Outdated gutters and penetrations Blockage or cracks in gutters, downpipes or ventilation ducts lead to flooding on the underside of the roof.

By tackling the problem directly and carrying out periodic inspections you can prevent many problems.

History and evolution of roof leak detection

In the past, roof leaks were often only discovered through visible water damage, after which everyone started demolishing. Over the years, the industry has undergone enormous technological advancements. Since the introduction of infrared technology, digital hygrometers, and tracer gas methods, demolition work has practically become a thing of the past. Collaborations with companies like FLIR (market leader in thermal cameras), Leica Geosystems (precision detection), and the broader use of ultrasonic detection now ensure speed, efficiency, and minimal disruption.

Our approach is suitable for both traditional buildings and modern roofs. By continuously investing in knowledge and equipment, we are always up-to-date and can flexibly adapt to the latest materials, such as EPDM or synthetic roofs.
